Boeing on Sunday (March.17) said it is finalising a software update and pilot training revision for its 737 Max aircraft, the plane that suffered two deadly crashes in less than five months.

He said "work is progressing thoroughly and rapidly" to determine the cause of the Ethiopian Airlines crash, which occurred shortly after take-off from Addis Ababa on March 10 and killed all 157 people on board.

"During the verification process of the FDR (Flight Data Recorder) data, clear similarities were noted by the investigation team between Ethiopian Airlines Flight 302 and Lion Air Flight 610, which will be the subject of further study during the investigation", the BEA said in a statement.

Fin24 reported earlier that the sovereignty, integrity and role of civil aviation regulators have become the focus of debate in aviation circles since the fatal crash of an Ethiopian Airlines Boeing 737 MAX 8. Stock losses have wiped around $28 billion from its market value since the Ethiopian Airlines crash. On Monday, the company's shares dropped by 1.8 percent in NY.

The subpoena, which came from a prosecutor in the Justice Department's criminal division, seeks documents and correspondence related to the plane, according to the report.

Separately, the US Department of Transportation's inspector general was also scrutinising the FAA's oversight of Boeing and the development of the 737 MAX, according to a person with knowledge of the matter who spoke on condition of anonymity.

It was only days later that US President Donald Trump announced the grounding of all Boeing 737 MAX 8s.

Boeing said it followed the rules in bringing the plane to the market.

The motors on the new plane are heavier than in the 737 NG, posing more of a risk of stalling, so the MCAS was created to protect against the possibility.

Under scrutiny is a new automated system in the 737 MAX model that guides the nose lower to avoid stalling, while Boeing has raised questions in the Lion Air case about whether crew used the correct procedures.

Boeing said the FAA had reviewed all data and concluded the aircraft "met all certification and regulatory requirements". The objective is to save on costs related to retraining pilots about the systems used in new models.

The two accidents proved to be a huge blow to Boeing.
